JTO ALL WHOM IT MAY CONCERN:

i Be it known that we, FREDERICK G. NIEDRINGHAUS and WILLIAM E.' NIEDRINeHAUs, both of the city and county of St. Louis, in the State of Missouri, have invented a new and useful Improvement in Kettles, of which the following is a full, clear, and exact description, reference being had to the annexed drawing, forming a part of this specification, and representing a side elevation of a. kettle embodying our improvement.v y

Our invention consists in forming the nose or spout of 'a kettle fromthe'bottom and top of same by press- .'ure; the kettle being made of two pieces of sheet metal. i A represents the top, and B the bottom of n kettle, formed by pressure from two pieces of sheet metal, and

united at the line d. C represents the noseor s-p'out formed from Aand B, Rndunted at the line d. -The spout may be made of any length by additions to sume, and yve do not intend to: limit ourselves to the spout I when completely formed inthis mann-er, but shell claim the application of this method of manufacture when only the base of thespout 'isfmade in the manner described, and the remaining portion is uttaehed thereto'. Spouts constructed in this wey cannot be melted off, and :is the kettle niay be transported inperts, there is also less liability to injury to the spout from breaking 0r jamming.A i y I 4 V We do not claim the method of constructing the kettle by pressure from two plates of sheet metal, since that is already protected by Letters Patent No. 67,425, ofV which Frederick G. Nedrnghaus, above named, is the sole owner by mesne assignments; `but What wedo claim as our invention, and desire to secure by Letters Patent, is l Y The spout of a. kettle when formed by pressure from the bottom and top plate of the kettle, when constructed substantially as shown and specified.
